BERNARD J. SCHMELZER, OF JULIET, ILLINOIS.

BUNG.

Application led November 11, 1913.

To allan/"mm it may concern Be it known that l, BERNARD J. SGHMELZER, a citizen of the United. States, residing at Joliet, in the county of `Will and State of Illinois, have invented cert'ain'new and useful Improvements in Brings, of which the following is a specification. l

This invention relates to improvements in bungs and has for its object to provide a new and improved form of bung which may be readily driven in the bung hole of a beer cask or the like to retain the contents there in under pressure and which may be readily removed therefrom.

Another Objectis to provide a bung of considerable durability as opposed to the or dinary wooden plug or bung now commonly used.

My invention contemplates the use of a metal retaining member carrying a packing ring preferably of expansive material which will frictionally engagel the bung sleeve or lining to prevent leakage therethrough and to retain the bung in position.

Still another object is to provide a bung of the class described which will permit replacementof the expansible ring when the same has become used up. This and other objects will be described and shown in the following specification and accompanying drawings, in which-V Figure 1 is a section through a portion of a barrel and bung hole thereof showing my improved bung in place; Fig. 2 is a perspective of one form of my improved bung; Fig. S is a vertical section through the same; Fig. 4 is a horizontal section along the line 4 4 of Fig. 3; Fig. 5 is a side elevation of a form of wrench which may be used with my improved bung.

Like numerals refer to like elements throughout the drawings, in which- 10 designates a cask or barrel provided with a bung hole in which is threaded or otherwise secured a sleeve 11 of suitable material and provided with the tapered inner wall 12, as clearly shown in Fig. 1.

13 designates generally one form of my bung comprising a body portion 14 of metal or the like having the non-circular socket 14'EL for engagement by a wrench or the like. This body portion 14 is provided with the depending stud or boss 15 externally threaded, as indicated at 16. The outer periphery of the body member 14 is externally grooved as indicated by numeral 17, this grooved Specification of Letters Patent.

portion extending from the lower part of body member 14 and terminating shortof the top thereof so as to provide a collar portion 18, as clearly shown in Fig. 3. Lugs or small shoulders 19 are formed on the member 14and extend outwardly from the outer periphery of the groove 17, as shown in Fig. 4. A packing ring 2O is provided with slots Yor grooves 21 corresponding with lugs 19,

and this collar or ring 9.() is constructed to fit closely around in the groove 17, the said slots 21 fitting over the lugs 19, thereby servino" to prevent relative rotation of thel cated by numeral 26, to correspond to the threaded boss 15 with which it engages when in assembled relation, as shown in Fig. 3. This follower is provided with the outwardly projecting non-circular head 27 adapted for engagement by a wrench vor the like so that it may be attached to or de-'` tached fromV the body member 14. This follower 25 is further provided with the dishedout upper surface 2S surrounded by the peripheral flange 29, this peripheral flange being located slightly outwardly of the` outer peripheries of the groove 17, as shown in Fig. 3. A washer or filler 30 is located on the dished-out surface 28 of the follower, the thickness of the same being preferably slightly less than the height of the peripheral flange 29. i

It will be apparent that in assembling the device, after the expansible ring Q0 has been fitted on the body member 14, the follower 25 carrying the washer 30, may be threaded on the boss 15 and screwed toposition wherein the peripheral flange 29 will contact with the ring 20. Further rotation of the follower 25 will force the ring against the collar or flange 18 of the body member 14 and will expand the ring 20 outwardly to-increase the external periphery thereof. The bung is then in condition to be utilized and when sealing a barrel may be lightly driven into the sleeve 11, as shown in Fig. 1, in which position it will be retained by the frictional contact of the packing ring 2O with the tapered inner wall 12 of the sleeve 11. This will' insure a tight joint between the bung and the sleeve and not only will serve to retain the bung in place, but will prevent leakage therearound of gas or fluid. The outer peripheries of the follower and body member being less than the inner di- Vameter of the sleeve 11, contact between the said elements is thereby avoided. .Vhen it isdesired to remove the bung it is merely necessary to insert the head 35 of a wrench or tool 36, and slightly rotate the same, whereupon the bung will become loosened in the sleeve and may be lifted therefrom.

In ordinary practice where wooden plugs are used, for example, and are driven in flush, as is necessary, it is necessary to use an auger or corkscrew or the like to extract themand they readily become broken or split and pieces of the wood fall into the contents of the barrel so that they are troublesome in that respect and also require more time and trouble in their extraction as well as insertion. Should the eXpansible ring 2O of my device become smooth or worn down so as to prevent atiO'ht fit thereof in the bung hole, the follower 25 may be advanced Von the boss 15 to further expand the ring and if vsuch expansion is notfsufficient, the follower lmay be removed and the washer V taken out of the same, whereupon further expansion ofthe ring is possible, as will be apparent from the construction of the follower. Furthermore, when the packing rings become finally worn out they are easily replaced, the metal members being comparatively indestructible and capable of use for a Along time'. l

It will be noted that the follower 25 is the only portion of the' bung which is inV contact with the contents of the barrel and it is preferable to construct this follower of some material such as aluminum which will not taint Vor contaminate the contents of the cask and'which is non-corrosive. I may provide other metal, however, suitably Vcoating or plating the same to accomplish the same object. Y

It is to be noted my improved bung comprises a packing ring of resilient material, the external periphery of which is of greater diameter than that of the adjacent surface of the other bung members, after the whole device is assembled and prior to its insertion in the bung hole of the barrel; This is in contradistinction to devices first placed in the said bung hole and then operated to expand a ring to force it into engagement with the wall of the bung hole. It will be obvious that bythe use of my device I may quickly drive the bung in the barrel and treat a numkber of barrels in a short period of time,

whereas in devices of the character mentioned, a relatively considerable amount of time is required in placing each bung, thereby eliminating them from consideration in practica-l use.

It will be apparent that while I have described and shown my invention specifically, it will be obvious that the same is susceptible of many modifications, and I do not wish to be restricted to the form shown and described, beyond the scope of the appended claims.

That I claim is l. A bung comprising a body portion having a non-circular socket on one side and a threaded stud on the other side, said body member being further provided with a portion of reduced diameter, a follower having a non-circular boss on one side and a socket threaded for engagement by said stud on the other side, said reduced portion of said body member being provided with lugs or the like, and a packing ring adapted to lit around said reduced portion of said body member and to be maintained in position thereon by said follower, said packing ring being constructed of resilient material and projecting beyond the adjacent surface of said body member and follower, said packing ring being provided with grooves or the like extending over said lugs of said body member whereby relative rotation of the latter with respect to said packing ring will Abe prevented.

2. A bung comprising a body member having a non-circular socket in one side and a threaded stud on the other side, said body member being further provided with a portion of reduced diameter, a follower having a non-ci-rcular boss on one side and a socket threaded for engagement by said stud on the other side, said follower being further provided with a recessed surface adjacent said socket, a peripheial flange surrounding said recess, and a packing ring adapted to fit on said reduced portion of said body member and to be maintained in position by said follower, said packing ring being of resilient material and projecting beyond the adi acent surface of Said body portion and follower, said body member being provided with lugs, said packing ring being provided with sockets to lit over said lugs whereby rotation of said packing ring relative to said body portion will be prevented.

In testimony whereof, I have subscribed my name.
